[112.10] Chandra images of the Pleiades

We present first results from a 60-ks image of the core of
the Pleiades cluster with ACIS-I on the Chandra X-ray
observatory. The observations were obtained as part of the
Cycle-1 GTO observations. The ACIS data will be used with
recently derived rotational periods to test
rotation-activity relations at the low end of the zero-age
main sequence. The ACIS spectra and light curves will also
allow modelling of X-ray flares and coronal heating for
these young, active stars.
